1. A method comprising:
processing a signal received from a sensor associated with an autonomous vehicle, the processing outputting a prediction indicating a likelihood that an emergency vehicle is present in an environment proximate to the autonomous vehicle;
receiving, at the autonomous vehicle, a vehicle-to-vehicle communication message from another vehicle that contains a notification of an approaching emergency vehicle;
generating a determination, based on the output prediction and the vehicle-to-vehicle communication message, that indicates whether an emergency vehicle is proximate to the autonomous vehicle;
in response to the determination indicating the emergency vehicle is proximate, causing the autonomous vehicle to perform an action;
wherein processing the signal received from the sensor associated with the autonomous vehicle comprises:
determining if behaviors of other vehicles in the environment of the autonomous vehicle indicate that the other vehicles are reacting to an approaching emergency vehicle;
in response to detecting behaviors that indicate the other vehicles are reacting to the approaching emergency vehicle, outputting the prediction indicating the likelihood that the emergency vehicle is present in the environment.
